HOlSTlNG -BUCKET.

Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed January 31, 1906- Serial No. 298,887.

To all whom it may concern:

Be it known that I, WILLIAM H. J ESSUP, a citizen of the United States, residing at Sheridan, in the county of Hamilton and State of Indiana, have invented a new and useful of the bucket controlled by the outhaul-cable,

features of the present invention. a view at right angles to Fig. 1.

so as to obviate the manual releasing of the bottom of the bucket when it is desired to dum the same.

With this object in view the invention consists in the combination'and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and articularly pointed out in the appended cFaims, it being understood that changes in the form, proportion, size, and minor details ma be made within the scope of the claims without departing from the s irit or sacrificing any of the advantages of t e invention.

In the drawings, Figure 1 is a side elevation of an excavating-bucket embodying the Fig. 2 is Fig. 3 is an enlarged fragmentary view of a detail of the invention, parts being broken away to show an antifriction-roller.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

The body 1 of the present bucket is of any approved shape and appropriate size with its top open and its lower end closed by a swinglng bottom 2, hinged at its forward edge, as at 3, and disposed upwardly from the bottom edges of the sides of the bucket when closed. At the front and rear of the top of the bucket are metal plates 4, riveted or otherwise secured to the outer side of the bucket and rising above the top thereof, the upper edges of the plates being provided with cutting edges which are beveled or turned outwardly. These plates not only serve as cutter or scraper blades for excavating purposes, but also brace and strengthen the top of the bucket.

For the purpose of suspending the bucketthere are bail members 5 lying at opposite sides of the bucket and received within vertical alined loops or brackets 6, secured to the exterior of the bucket, the lower end of each bail member being hooked, as at 7, so as to embrace the bottom of the adjacent lower loop or bracket. The bail members converge across the top of the bucket and terminate in substantially parallel upstanding portions 8, which are ierced by a pin or cross-bar 9. A yoke or c iplO embraces the terminal ears 8 of the bail members 5 and is pierced by a pin or bar 9, there being a pulley or suitable guide 11 provided upon the top of the clip through which runs a hoistingcable 12. A pair of spaced links or hangers 13 depend from the pin or cross-bar 9 and support an upstanding lever 14, which is received between the links or hangers and fulcrumed thereon at their lower ends by a suitable pivot-pin 15. This lever works in rear of the pin or cross-bar 9 and rises above the latter, the forward edge of its upper portion being reduced to form a transverse shoulder 16, which is adapted to take under the pin per end of the lever above the pin or cross- 7 bar 9 and connected to a suitable windingdrum, (not shown,) whereby the bucket is drawn forwardly to the position Where it is to be dumped.

In practice the bottom of the bucket being closed by reason of the lever 14 being held against the pin or cross-bar 9 by the pull on the cable 18, the bucket is filled in any suitable manner, after which it is hoisted by the cable 12 and then drawn to any desired 0- sition by the pull-cable 18. When the buc et reaches its destination, the windin drum for the cable 18 is released, thereby re easing the lever 14 and permitting the weight of the material in the bucket to open the hinged bottom 2, and thereby promptly dump the bucket in a positive manner.

From the foregoing description it will be understood that the present invention dispenses with latches and similar locking ver 14, thereby dispensing with the services of an attendant at the location of the dumping of the bucket to release the bottom thereof.

To prevent wear upon the rope 18, a rotatable sleeve or spool 19 is fitted upon the pin 9 between the han ers 13, the rope being adapted to engage t e sleeve when the bottom of the bucket is open.

Having thus described the invention, what is claimed is 1. A hoisting-bucket having a dumpingbottom, a suspending-bail for the bucket, a bracket hung from the top of the bail, an upstanding lever iulcrnmed upon the bracket and rising above the top of the bail for contact therewith to limit one direction of movement .of the lever, and a connection betwee the lever and the bottom of the bucket.

2. A hoisting-bucket having a dumpingbottom, a suspending-bail for the bucket, a yoke rising from the top of the bail, a pulley carried by the yoke, a bracket hung from the top of the bail, a lever fulcrumed upon the bracket and rising above the top of the bail for contact therewith to limit one direction of movement of the lever, and a connection between the lever and the bottom of the bucket.

3. In a hoisting apparatus, the combination of a bucket having a dumping-bottom, a suspending-bail for the bucket, a pulley connected to the top of the bail, a hoisting-cable engaging the pulley, a bracket hung from the top of the bail, an upstanding lever fulcrumed upon the bracket and rising above the top of the bail for contact therewith to limit one direction of movement of the lever, said lever having a locking-shoulder to engage beneath the top of the bail, a pull-cable connected to the lever, and a connection between the lever and the bottom of the bucket.

In testimony that I claim the foregoin g as my own I have hereto afljxed my signature in the presence of two Witnesses.

WM. H. J ESSUP.
